"We have tried to identify everyone who was in the restaurant," Fennelly says. "We found other people in the restaurant. We looked for other video surveillance in the area."

Fennelly says officials are looking for the people shown in the photos taken at the restaurant during the fight.

One of the men has tattoos of writing on both hands. Another photo shows a 2000-2002 Chevy Monte Carlo.

"There is an individual depicted in a number of the pictures who we believe was with the shooter. He was inside the restaurant, then he was outside, so we are asking for the public's help if anybody recognizes him and that will lead us to the shooter."

The restaurant is no longer open 24-hours a day and has since increased security.
